Queries the duration of the last completed acquisition. The result may depend on the spacing of the
triggers in sequence mode, and it may depend on the number of averages when a channel is
in averaging mode.
AcquisitionDuration
From 1e-012 to 1e+012 step 1e-015
Double
' Visual Basic Script
Set app = CreateObject("LeCroy.XStreamDSO")
' Obtain the duration of the last completed acquistion.
AcqDuration = app.Acquisition.Horizontal.AcquisitionDuration
MsgBox AcqDuration
Range
Example
Description
Sets/Queries the maximum permissible number of samples to be used in the acquisition memories.
At the faster sample rates, the actual number used may be less than this maximum.
MaxSamples
From 500 to 16000 step 10, locked to 1 2.5 5, fine grain allowed=true, on=false
DoubleLockstep
' Visual Basic Script
Set app = CreateObject("LeCroy.XStreamDSO")
' Set the available memory length per channel to 500
app.Acquisition.Horizontal.MaxSamples = 500
Range
Example
Description
Queries the sampling rate. This is the effective sampling rate of the traces, rather than the sample
rate of the ADCs.
SamplingRate
From 500 to 1e+013 step (2 digits)
Double
' Visual Basic Script
Set app = CreateObject("LeCroy.XStreamDSO")
' Inspect the effective sampling rate of the signal.
SamplingRate = app.Acquisition.Horizontal.SamplingRate
Range
Example
Description
Sets/Queries time base variable step On/Off
